SuperSTAT SZ1051

Introduction

Congratulations on choosing the SuperSTAT™ Thermostat SZ1051! The SuperSTAT series of thermostats are feature rich, multifunction devices providing extensive controls across a wide range of HVAC applications.
Complete the configuration after installation (refer to the SZ1051/1053 SuperSTAT Installation Manual for instructions on mounting the device, wiring the communications network and connecting other devices to the SuperSTAT.) Your configuration settings will be uploaded to Ubiquity Cloud the first time you make a connection to the site. Alternatively, you can skip configuring the SuperSTAT via the keypad and perform all configurations via Ubiquity Cloud, or via a PC running TCS Insight software, which is available for download on the TCS website.
NOTE: When configuring the SuperSTAT via a connected PC, you must first set the SuperSTAT’s address, baud rate, and temperature scale using the keypad (see “Programming Keypad Access” on page 4).
If you have any questions regarding your SuperSTAT, do not hesitate to contact TCS Technical Support at 800.288.9383, ext. 2. Our Technical Support Department hours are Monday – Friday, 7:00 a.m. to 7:00 p.m. (CST).

Display Screen and Keypad

The display screen on the right side of the cover provides at-a-glance information including day, date, time, and temperature (based on sensor selection and wiring).

Locating the Programming Keypad
The SuperSTAT is programmed through a keypad behind the panel on the left side of the cover. Access the keypad by swinging open the cover panel.

Programming Keypad Access
The keypad can be configured to restrict access to the Programming Setup and Clock and Schedule functions. You can control the access to either function by configuring the keypad dip switches on the inside of the front cover as shown.

Navigating Via Keypad

All settings on the SuperSTAT can be made via the keypad. Each screen will display the name of the setting, a selection option, and current values for that screen, which will flash to indicate which is active. Pressing the WARMER button will increase the value or advance the active setting to the next option on the screen; pressing the COOLER button will reverse the process. For screens with multiple values (e.g., date setup), pressing the OVERRIDE button will advance you to the next value. After adjusting the values, press the PROGRAM SETUP or CLOCK SETUP button again to save the values and advance to the next screen.
NOTE: Press and hold the PROGRAM SETUP, CLOCK SETUP, WARMER, or COOLER buttons in order to scroll through screens and values more quickly. Press the SERVICE STATUS button to exit PROGRAM SETUP Mode or CLOCK SETUP Mode and return to the main screen.

Keypad Button Functions

Program Setup Mode

Before entering PROGRAM SETUP Mode, ensure that the temperature sensor dip switch settings match your intended use (see the SZ1051/1053 SuperSTAT Installation Manual). If the dip switch settings do not match the configuration settings in this section, the SuperSTAT will not function properly.
NOTE: PROGRAM SETUP Mode can be disabled via dip switch settings (see “Programming Keypad Access” on page 4, or access can be restricted by requiring an access code (see “Keypad Access Code” on page 10).
The main screen displays when not in PROGRAM SETUP Mode or CLOCK SETUP Mode. The SuperSTAT will revert to this screen if no entries are made after 10 minutes.
From the main screen, press the PROGRAM SETUP button on the keypad to configure the settings.
If the SuperSTAT has been configured to require an access code to enter PROGRAM SETUP Mode, this screen will appear (see “Keypad Access Code” on page 10). If you enter the wrong code, the screen will revert to the main screen.
